My van was stalling around every 5 to 7 minutes while driving, eventually it just stopped running. I was told my fuel pump was shot. I started small and changed the relay, filter and even the ignition module before I changed the pump. Even with all of this being new the injectors still aren't receiving fuel. Do you have any ideas which direction I need to go now

Is there any fuel pressure at the fuel rail? If the pump is new, can you hear it run? If not, did you check for power to the pump? Also, if the pump runs, has fuel pressure at the rail. Are the injectors getting power? Will the vehicle start for a couple seconds if you use starting fluid?

Yes it is a new pump and it's not kicking over like it should when I try to start it. I checked for power to the pump and it reads all green lights for all 7 wires so I am lost. It will start when I put fluid in the injectors but only last a few seconds. Could you please tell me where and how I check my fuel rails. Any other advice I could get would be appreciated. Thank you

Okay, for sure it isn't getting fuel to the engine. Here is a fuel pressure and regulator test video. Do this and let me know what you find. Also, I'm not sure what you mean when you say all lights are green on all 7 wires.

My wattage tester I use to check for output, I had used it for the wiring harness I replaced to the fuel pump and all the wires read good as far as getting current, the fuel pump won't kick on as it should. Your saying my injectors aren't getting fuel, how do I check my fuel rails if that still may be the issue. Could it be some bad wiring somewhere I wonder. I followed my wiring from the pump all the way back and they all seem to be ok so other than me getting it towed to a shop I'm at a loss

Ok I watched the video you linked to me, I checked the fuel pressure prior to replacing the pump and I had none. I did not check the regulator though. Should I check the pressure again.

If the pump isn't running, you won't have pressure. You mentioned that all the wires had power at the pump. That shouldn't be. One should be a ground.
